SPEARS’ STAY IN PSYCH WARD TO BE EXTENDED

It's not a done deal, but expect that sometime tonight, papers will be signed at UCLA extending Britney Spears' stay at the psych ward — by 14 days.

It's an internal process — done without a court order. But we're told it will indeed happen, and that's not surprising given her mental health. As we first reported, Britney's been diagnosed with severe bipolar disorder.
